Answer:
Substance S is GLYCEROL.
Explanation:
To know what substance S represent, let us determine the density of substance S.
From the question given above, the following data were obtained:
Mass of S = 92.09 g
Volume of S = 73.09 mL
Density of S =..?
Density = mass /volume
Density of S = 92.09/73.09
Density of S = 1.26 g/mL
Finally, we shall determine what substance S represent as follow:
Comparing the density of substance S (i.e 1.26 g/mL) with those given in question above, substance S is GLYCEROL.
Answer:
Explanation:
The unbalanced nuclear equation is
Let's write the question mark as a nuclear symbol.
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
60 = 0 + A, so A = 60 - 0 = 60, and
27 = -1 + Z, so Z = 27 + 1 = 28
Your nuclear equation becomes
Element 28 is nickel, so the balanced nuclear equation is
Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
